UNDATED, WI  (WTAQ) - Factory business kept growing this month in southeast Wisconsin, but at a slower pace than in February. The Center for Supply Chain Management at Marquette University said its manufacturing index for March was 51.78. That’s down seven-percent from February. But it was still a positive number, since anything above 50 indicates growth. The report also showed that new manufacturing orders dropped by an average of 16% in the Milwaukee area from February. But company executives who were surveyed remained positive – and some said they were running at their full capacity. The report was prepared for the Institute for Supply Management, a group of Milwaukee area purchasing directors.
